Answer: x < 4
Step-by-step explanation: You are trying to isolate the variable, x, so you have to subtract 1 on both sides of the inequality. Then, you are left with x < 4.
Answer:Solve. 2a + 3b = 5 6= a -5 a = 4 b = -1 1 a = 6 b=1 a=6 6 = -1 a=4 6 = 1

Answer:
y = 1/2 x + 3
Step-by-step explanation:
the positive 3 is the y intercept and the positive 1/2 is rise over run up-1 & 2 to the right
Answer:
$542
Step-by-step explanation:
we know that
The equation of a exponential decay function is given by
![y=a(1-r)^x](https://tex.z-dn.net/?f=y%3Da%281-r%29%5Ex)
where
y is the value of the lawnmower
x is the time in years
a is the initial value
r is the rate of change
we have
![a=\$600\\r=2\%=2/100=0.02](https://tex.z-dn.net/?f=a%3D%5C%24600%5C%5Cr%3D2%5C%25%3D2%2F100%3D0.02)
substitute
![y=600(1-0.02)^x](https://tex.z-dn.net/?f=y%3D600%281-0.02%29%5Ex)
![y=600(0.98)^x](https://tex.z-dn.net/?f=y%3D600%280.98%29%5Ex)
For x=5 years
![y=600(0.98)^5=\$542](https://tex.z-dn.net/?f=y%3D600%280.98%29%5E5%3D%5C%24542)
